Abstract

The utility model relates to a lamina lock without spring wings. The utility model comprises a lock shell, a lock core and a lamina. The lock core is provided with a lamina slot inside. The lamina is arranged in the lamina slot. A key positioning mechanism is arranged between the lock shell and the lock core. The key positioning mechanism comprises a positioning lamina, a positioning board and a positioning spring. The positioning board is movably arranged in the lock core in the radial direction. The positioning lamina is arranged in a positioning slot of the positioning board, and is matched with the positioning board at the locking position. The positioning spring is arranged in a spring slot of the positioning lamina. A key jack of the positioning lamina is provided with convex blocks which are matched with concave pits on a key. The utility model is provided with the beneficial and technical effect that because the lock is provided with the key positioning mechanism, the utility model can be unlocked only when the key is fully inserted. Therefore, the utility model has the advantage of good theft-proof performance.

Description

Spring-free blade locking head

Technical field:

Relate to a kind of lockset in utility model, relate in particular to a kind of padlock head.

Background technology:

At present, the blade lock is a kind of lockset commonly used, common padlock head locks lock core by blade or lock core pin and rotates, and this tapered end comprises lock housing, lock core, blade etc., and blade is arranged in the blade groove of lock core, when inserting key, each blade is from the locked groove of lock housing in the retraction lock core, or after the blade alignment, the groove shaped of different blades is in alignment, lock core pin snaps in the blade groove, can unblank by rotational lock core.This blade lock is because the idle stroke feature of blade, when key is not inserted into, also can moving blade, and there is the shortcoming of theftproof performance difference.In addition, key can not self-return during the tapered end locking of prior art, uses inconvenient.

Summary of the invention:

Technical problem to be solved in the utility model overcomes the deficiencies in the prior art exactly, and a kind of simple in structure, spring-free blade locking head that theftproof performance is good is provided.

The utility model solves the problems of the technologies described above the technical scheme that is adopted: spring-free blade locking head, comprise lock housing, lock core and blade, in lock core, offer blade groove, blade is placed in one, between lock housing and lock core, also be arranged on key positioner mechanism, described key positioner mechanism comprises locating blades, location-plate and retainer spring, location-plate radially is arranged in the lock core versatilely, locating blades is arranged in the locating slot of location-plate, cooperate with the location-plate lock-bit, retainer spring is arranged in the spring groove of locating blades, is provided with projection in the key hole of locating blades and is complementary with on the key pit.

Useful technique effect of the present utility model is: at first owing to be provided with key positioner mechanism on tapered end, have only when key is inserted into, just can unblank, thereby have the good advantage of theftproof performance, secondly, when the torsion spring on the location-plate can make locking, the key self-return, have advantage easy to use, the 3rd, the groove shapes that cooperates with lock core pin on blade and the lock housing has makes the blade advantage of return flexibly.

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is the A-A cutaway view Amplified image of Fig. 1;

Fig. 3 is the structural representation of blade;

Fig. 4 is the structural representation of the groove of lock housing.

The specific embodiment:

The utility model is described in further detail below in conjunction with drawings and Examples:

As shown in the figure, spring-free blade locking head, comprise lock housing 2, lock core 10 and blade 9, in lock core 10, offer blade groove, blade 9 is placed in one, between lock housing 2 and lock core 10, also be arranged on key positioner mechanism, described key positioner mechanism comprises locating blades 4, location-plate 3 and retainer spring 5, location-plate 3 radially is arranged in the lock core 10 versatilely, locating blades 4 is arranged in the locating slot of location-plate 3, cooperate with location-plate 3 lock-bits, retainer spring 5 is arranged in the spring groove of locating blades 4, establishes in the key hole of locating blades 4

There is the pit 11 on projection 8 and the key 1 to be complementary.

Also be provided with the torsion spring 6 that makes location-plate 3 reset and rotate between described location-plate 3 and the lock core 10.Also be provided with lock core pin 7 between described lock housing 2 and the blade 9, the cross section of the groove 12 on the blade 9 that is complementary with lock core pin 7 is a dovetail groove, and the cross section of the groove 13 on the lock housing 2 is the arc straight-line groove.

Its course of work is as follows: when unblanking, after key 1 was inserted into the position, locating blades 4 can withstand the pit 11 of key under retainer spring 5 effects, open location-plate 3 (making location-plate be in rotatable state) simultaneously; Key 90 degree, the different helical teeth of key are with after blade 9 aligns, and the groove shaped of different blades is in alignment, and lock core pin 7 snaps in blade groove 12, at this moment can drive lock core 10 rotations, by the stop that is connected with lock core, reaches the purpose of unblanking.

When shutting, lock core 10 receives the moment of torsion rotation that stop transmits, and ejects lock core lock 7, and the lock core return finishes; Under torsion spring 6 effect, key, blade rotation are got back to initial position, extract key after, locating blades 4 blocks location-plate 3 under the effect of retainer spring 5, the process of shutting finishes.
